Toni Collette stars as a surgeon forced to make a horrible decision to save her family from a rogue FBI agent (Dylan McDermott) in "Hostages."

In tonight's TV Picks, it's the final sing-off on "Idol" and several favorites bow out for the season.

But first, let's take a look at CBS's new fall schedule, which adds four new comedies and two new dramas to its successful mix.

Mondays: "How I Met Your Mother" stays put for its ninth and final season and, as viewers saw in this week's finale, (SPOILER ALERT) we've now met the mother, played by Cristin Milioti of Broadway's "Once." (Tangential area connection: She starred there with Claude's Elizabeth A. Davis and Amarillo's Erica Swindell.) Producers say the entire final season will take place during the wedding of Barney (Neil Patrick Harris) and Robin (Cobie Smulders). That's followed by new comedy "We Are Men" with Jerry O'Connell and Tony Shaloub heading up a cast of bachelors in an apartment complex. "2 Broke Girls" stays in place, leading into a new Chuck Lorre comedy, "Mom," with Anna Faris as a recovering alcoholic single mom and Alison Janney as her hypercritical mother. Then, CBS plays with cable-style scheduling with a pair of short-run dramas sharing the 9 p.m. slot -- "Hostages," a new drama from Jerry Bruckheimer, starring Toni Collette as a surgeon ordered to kill the president (James Naughton) to save her family; and "Intelligence," a thriller with Josh Holloway ("Lost") as a man given a supercomputer brain implant. ("Mike & Molly" will return midseason with a full 22-episode order.)

Tuesdays: "NCIS" and "NCIS: Los Angeles" will stay in place, followed by a relocated "Persons of Interest." This might have been an all-"NCIS" night, but "NCIS LA: Red," which got a backdoor pilot this spring, didn't make the cut.

Wednesdays: Nothing changes, with "Survivor," "Criminal Minds" and "CSI" all staying in place.

Thursdays: The network looks to be attacking NBC's vulnerability by going with a four-comedy block. Top comedy "The Big Bang Theory" stays in place, followed by "The Millers," starring Will Arnett as a TV news reporter whose divorce inspires his dad (Beau Bridges) to leave his mom (Margo Martindale). At 8 p.m. is another new sitcom, "The Crazy Ones," featuring Robin Williams' return to series TV as an unpredictable ad exec and Sarah Michelle Gellar as his straight-laced daughter. "Two and a Half Men" moves to 8:30 p.m., followed by the returning "Elementary."

Fridays: "Undercover Boss" returns to the fall season, followed by "Hawaii Five-0" in its new time slot. "Blue Bloods" stays in place.

Saturdays: Comedy and crime show repeats, plus "48 Hours" at 9 p.m.

Sundays: No changes -- "60 Minutes," "The Amazing Race," "The Good Wife" and "The Mentalist" all stay put.

"Arrow" (7 p.m. on The CW, cable channel 11): Buzz for this series has far surpassed my expectations, so I'm thinking of a summer catchup. In tonight's season finale, Oliver (Stephen Ammel) races to stop the Dark Archer (John Barrowman).

"The Middle" (7 p.m. on ABC, cable channel 8): Frankie (Patricia Heaton) is confused for a doctor thanks to her dental-assistant's lab coat, a misapprehension she's in no hurry to correct.

"So You Think You Can Dance" (8 p.m. on FOX): Audition rounds continue in Detroit and, with any luck, no one's dislocated knee will get slow-motion, close-up replays. (I'm still nauseated from last night's premiere.)

"Modern Family" (8 p.m. on ABC): Phil (Ty Burrell) wants to take the family on a road trip in his new RV, and Cam and Mitchell (Eric Stonestreet and Jesse Tyler Ferguson) get uber-competitive at Lily's (Aubrey Anderson-Emmons) gymnastic meet.

"Law & Order: SVU" (8 p.m. on NBC, cable channel 5): The detectives try to identify an unconscious woman found floating in a river near the mayor's home.

"Supernatural" (8 p.m. on The CW): The eighth season wraps up with Sam and Dean (Jared Padalecki and Jensen Ackles) trying to keep Crowley (Mark Sheppard) from undoing all of their good work.

"How to Live with Your Parents (for the Rest of Your Life)" (8:30 p.m. on ABC): Polly (Sarah Chalke) decides to go back to school.

"CSI" (9 p.m. on CBS): One of the team goes undercover to capture a "Dante's Inferno"-inspired serial killer.

"Chicago Fire" (9 p.m. on NBC): Casey (Jesse Spencer) is forced to work with the dirty cop (Jason Beghe) who tried to kill him.

"Nashville" (9 p.m. on ABC): Avery (Jonathan Jackson) and Will (Chris Carmack) both get lucky career breaks.
